I'll help you out with 3 questions.
For #1, you kind of figured it out yourself
That 90 degree angle on paper means that m/1 and m/2 make up 90
If m1 is 50, then just subtract m1 (50) from 90, making it 40. m/2 is 40
If Angle M4 is 45 degrees then angle M3 is 180-45 since they both make up a 180 degree angle.
There are 180 degrees in a triangle
If m 8 = 78
and m 9 = 60
m 10 is 180 - 78 - 60
Answer:
17 out of every hundred students
Step-by-step explanation:
deltax = (56-0)/4 = 14
number of intervals 4
The intervals are:
(0,14),(14,28),(28,42),(42,56)
The Midpoint Rule =
f(7)+f(21)+f(35)+f(49)
[0.47577]+[-0.99159]+[-0.35892]+[0.65699]
deltax =14
sum = -0.21774
Multiplying by deltax = -3.0484
Multiply 191 and 365 and get 69,715
Change it to a percentage 0.03%
